There is'a space 28 between each carrier and the front of the support 26 to allow independent adjustmentof the carriers laterally and springs 30, which are'of less strength than thespring 22, are interposed between these members and tend-to move each carrier-forwardly to normalposition. The series of adjustable carriers 18,

after lateral adjustment, (eifccted by pressing a heel rearwardly against the disks 10) can be clainped'between a flanged collar 32 and a collar 34. The collar 32'is loose but not rotatable. on the support 26 and the other collar 3 is fixed to the support. The springs 22', being stronger than the springs clamped in adjusted position. The support '26 at one endpasses through a slot in a rocking bearing bracket 36', there being a nut 38 threaded on the end of the support to clamp the carriers between the collars 32 and 34:.

The burnishing disks are rotated. by the following mechanism: A disk 40 has its hub rotatably supported onan extension 42 of the support 26 and near its periphery has a member 4-4 pivotally connected to jointed sections 46 and 4C8 which constitute a drive pin extending horizontally through rectangular slots 50 in the burnishing disks 10. These jointedsections allow the disksto be driven without cramping as theyoseillate with the support 26 and rotate about centers that are laterally displaced. The disk 40; is connected by a universal joint to a short shaft 62 in turn'connected through auniversal joint 6% to adrive shaft 66. The universal iCll'lL'G is necessitated by the fact that the tool oscillate-s as well as rotates. The tool is easily removable as aunit: on account of'the provision of a detachable cap plate which retains the end of thesupport 26 to the bearing bracket 36. Upon removal of the cap plate, the left'end of the support 26 can be swung forwardly and its nae nose ing plates 76 and 78 in the form of U-shaped castings (Fig. 2) which lie along the op posite side of the tool and embrace the support. These plates being open at the front do not interfere with removal of the tool. They are connected and braced at their forward ends by detachable rods 80 and 82. Each plate. carries an upper heating unit at (Fig. 3) and a lower heating unit 86, one heating plate lying at the side of the outside burnishing disk 10 and the other lying at one side of the disk 40 thereby conducting the heat to the peripheries of the rubbing rs. Lead wires 87 extend from the heat ing units to a connection block 88 hung from the rods 72 and? #1 and spiral spring loads 89, under compression, connect the block 88 with a block 90 fixed on the frame and con nected with a source of current.

To avoid tool marks on the work, the tool is oscillated during rotation about an upright axis aassing through the central portion of the tool. An extension 91 (Figs. 1 and 3) of the rocking bearing bracket 36 is bent into alignment with the center of the tool and clamped to a vertical shaft 92, the upper end of which has a tapered bearing in a frame arm 94. The lower end of the shaft 92 is received ina cupped bearing 96 adjustably threaded in a lower frame arm 98. A. rearward arm 100 joined to the e);- tension 91 is connectedby a link 102 (Fig. 1) with an eccentric 104: on a substantially vertical shaft 106 driven by spiral gears 108 from the main drive shaft. A balancing member in the form of a weight 110 is rockably mounted on the shaft 92 and has an arm 112 connected by a link 11s with an eccentric 116 on the shaft 108. The tool and the weight are rocked simultaneously in opposite directions, this being effected by placing the high points of the eccentrics 180 apart, or in an opposite phase. The eccentrics and shaft are confined Within a casing 118 extending downwardly from the frame. Thus the burnishing rings or disks 10 are oscillated slightly from side to side, as they are rotated, and tool marks are avoided. a a

The finishing medium or war; is supplied from a receptacle 122 3 and l) carried above the tool on a bracket which is vertically adjustable 011 the frame. A heating unit 12% is inserted 111 a boss at the til) thence to an opening 130 (Fig. in the collar 32 whence a duct 182 (Figs. 5 and 6) through the support 26 carries the wax to the interiorof the tool. From this point the actuation of the tool causes'the wax to spread outwardly not only lubricating the ball bearings 12 and the contacting surfaces of the end disk with thellange of the collar 32 but. also supplying the periphery of the tool with the necessar finishing medium.

Two screws 13a, 3} are threaded into the upper arms of the heating plates and carry a spring pressed bar 136 having a pad or scraper 138 (Fig. 1) lying against the periphey of the tool to distribute the wax evenly over the surface. An auxiliary wax applying mechanism igs. 8 and 1) is provided comprising a pat 1 10. carried by an arm hungon the pivot rod 14:2 at the front of an arm Mtconstructed as an open fran'ie which is lar e enough to embrace the sides of the receptacle. 'lhe-arrn or frame 14% is pivotally connected bya rod 1&6 to the ends arnisO and 152 fixed to a rock shaft 15a journaled in a fixedbearing 156 on the frame. The wax applying member is oscillated-froina position in'co-ntact with the periphery of the tool to a position above the wax receptacle by a slotted arm 158 (Fig. 3) fixed to the rock shaftlo l and receiving va slide block 160 connected by a pinto a pulley 162 rotatably mounted on the bracket 120; The pulley is driven by a belt 161 from a second pulley 166 fixed to a shaft 168 driven by gears 170 (Fig. 1) from a second shaft 172, in turn driven by a spiral gear 17 i'neshing with a gear 176 (Fig. 3). on the shaft 106. The path of movement of the wax applying member is controlled by a projection 182 (Fig. 4:) from the arm 14A- whioh rides on a cam surface 18-1 fixed to the wax receptacle. The pad 1 10 is retained at the proper angle by rod 186 pivotally connected to the arm 150 and to an extension on the pad carrying arm.

At times, both means for applying war; will be used. At other times, the auxiliary mechanism will not be needed. Accordingly, the pad is yieldinglyheld in one of two positions, either against the periphery of thetool or in a raised position, by a spring 192 (Figs. 1 and 3) interposed between a pin 190 on the arm 11% and a pin 19% on a lever 196 which is hung on the rod M6. The effect of this spring 192 is varied, at the will of the operator, by swinging the lever 196', inovenientof which in one direction is limited by a short arm 198 which contacts with a pin 200 on the arm 152. lVhen the lever 196 is in the position shown in big. 3, the pad 1 10' is depressed by the spring and the auxiliary mechanism is'etlective. 1f the operator rocks the lever 196 about the rod 146 until its long arm contacts with the pin 200, the line of the spring will lie above the rod 1516 and hence retain the arm 14% in a raised position with the pin 190 resting against an extension 202 of the arm 152, thus renderingwthe auxiliary mechanism ineffective.

As the pad rec is swung above the ferward po ion of th wax receptacle, wax is transferred from the receptacle to the pad by a transferrer soc carried on arms 208 pivotally mounted at 2 0 at the rear of the receptacle. The transt'e Mr is actuated by the movementof the a pplying member, there being a bell crani-z lever pivoted on the transferrer arin S ant ying'in the path,

1 i 1 16 approaches ferror from {TC under side of he p tuation of the tran c cold, a rearwardly extending arm 21% on the bell crank l ver has interposed between it and an extension 218 of the 1 208, a spring 216. This spring will give, if any abnorn al resistance to the increment of the transferrer is encountere A curved tread r t (Figs. 1 and 3) "or the heel of a shoe is mounted adjacent o the periphery of" the tool on a rod 228 "'l1iCl has sliding adjustment parallel to ie tool axis. A lever having a cam "ace '26 is pivoted to the rest and is. deigned to aid the operator in pressing seine f the rubbing disks 10 rearwardly against he tension of the springs and when l dish carriers 13 are set free by loosening clampin nut 38. The operator is thus {bled to ect just enough disks to cover wort: being treaued and the others, or

right of the tread rest, are niovle to inoperative position where they are ld by their carriers on again turning up he clanrpnut 38.
